This RC mid-chassis support is intended for TAMIYA Scania R620 tractor truck kits and comes as a 3pcs alloy set TRU009SC. It serves as a reinforcement and tuning aid to strengthen the central section of the chassis and to offer consistent mounting points for suspension and drivetrain linkages.
The alloy part is used to replace stock plastic brackets or weaker supports so you get less deflection under load and more reliable alignment when setting up the truck. Installation normally matches existing chassis holes and hardware to keep modifications to a minimum; confirm fitment, then apply thread lock to steel fasteners if needed.
From a tuning perspective the mount is a practical mechanical upgrade: reducing mid-chassis deformation preserves suspension geometry and drivetrain alignment when you alter ride height, suspension travel or load balance.
Choose this support for stronger centre-chassis backing on scale tractor truck builds, and verify gearbox and suspension clearance before final fitting.
